Title: Lens meter
Inventor: ISHIHARA TAKETOSHI
IPC: G01M11/02
Filed: 1989-10-06
Abstract: PURPOSE:To discriminate between a right-eye lens and a left-eye lens while measuring optical characteristics by giving a lens to be worked an identification mark together with a positioning mark. CONSTITUTION:The lens L to be worked is mounted on a measurement optical storage part and its optical characteristics are measured; and a discrimination means decides whether the lens L is for the right or left eye according to prescription data which is inputted from an IC card. When the marks are added, a lever 23 is fallen to the horizontal attitude to set a rod 30 facedown and the lever 23 is pressed down. Consequently, an elevation part 21 moves down and the tip of the rod 30a abuts on the lens L to give the mark. At this time, a discrimination signal showing whether the lens L is for the right or left eye is sent out of the discrimination means to an electromagnet 40 associatively with the falling operation of the lever 23 to the horizontal attitude and a magnet 36 is put in leaving or approaching motion. Then a positioning rod 31 gives positioning marks at three positions and an identification rod 32 gives the identification mark at one position simultaneously.

Abstract: PURPOSE:To make the erasing of a background in higher speed and accuracy without an effect of the delay with a smoothing circuit by integrating an A.C. signal for the optional time after making a synchronous rectification for the decision of a zero level. CONSTITUTION:Electrodes 3-6 are housed in a cell 1 measuring the electric conductivity, wherein an electrolyte 2 is made to flow, and the A.C. voltage is impressed to the electrode 3 and the electrode 6 is at a ground potential. An impressed voltage control circuit 8 is controlled by the signal of a differential amplifier 7, and the potential between the electrodes 4,5 is made to be constant, then the corresponding A.C. voltage is outputted also from the amplifier 7. An output current from the cell 1 is converted 9 to a voltage and outputted as a D.C. voltage through a synchronous rectification circuit 11 and the smoothing circuit 12, where the synchronized signal 10 is a reference clock for the circuit 11 and a control circuit 17 for section integration time. Then, a integrator 13 performing the section integration for the synchronous rectification signal is decided as zero output in a zero detecting comparator 15. Finally, the section integration is performed in the circuit 17 synchronizing to the circuit 11, and the correction is decided to be finished with a zero result.

Title: Rf communication unit and its inspection method
Inventor: KOSAKA MASARU
IPC: H04B1/38
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To reduce the number of parts and to inspect an RF communication unit positively by allowing one portion of a circuit board including an antenna- mounting part to project toward the outside of a chassis. SOLUTION: One portion of a circuit board 11 projects to become a projecting part 11a where an antenna-mounting part 16 for mounting an antenna or a connector for coaxial cable is provided. The large part of one side of a circuit board 11 projects from a shield case 12 as the projecting part 11a, so that strength cannot be damaged greatly. Since an antenna or the like is directly mounted to the antenna-mounting part 16, the number of parts for connection decreases and costs can be decreased. Two test electrodes for testing the circuit board 11 are formed on the reverse side of the projecting part 11a, and one of them is electrically connected to the antenna-mounting part 16. In this manner, a test electrode is formed at the projecting part 11a, thus easily testing an RF communication unit.

Abstract: PURPOSE:To realize a gain switching amplifier circuit suitable for IC processing by keeping a current flowing to a load resistance constant to make the bias of an output voltage constant. CONSTITUTION:A bias adjustment transistor(TR) Q20, bias adjustment resistors RE 20-22, bias changeover switches SW 20-22 and base bias resistors RB 20, 21 are provided newly to a conventional gain amplifier circuit.
